ABSTRACT:
Aggregated fragment acknowledgement in a LAN. A transmitter sends a data packet to a receiver. The receiver then constructs an AFAF and sends that AFAF back to a transmitter. The transmitter is then able to determine the success and/or failure, in full or in part, of the transmission of the data packet to the receiver. A very precise granularity, or resolution, of the success of the transmission may be achieved on a per fragment basis. Bandwidth savings may also be achieved. When no resolution on a fragment basis is required, then that level of resolution is not employed. The resolution of the fragment basis may be adaptively employed when required to notify the transmitter of the status of one or more fragments within a data packet.
